B. F. CAUFFMAN, OF MILLERSTOWN, PENNSYLVANIA.

Letters Patent No. 73,779, dated January 28, 1868.

IMPROVEMENT 1M CANE-MILLS.

To ALL WHOM IT MAY concerns:

' Be it known that I, B. F. CAUFFMAN, of Millerstown, in the county of Perry, .and State of Pennsylvania, have-.invented a new and improved Cane-Mill; and I dohereby declare the'following to be a full, clear, and

exact description of' the same, reference being had to the nccompanyingdrawings, forming part of thisspecifi cation, and in which Figured represents a side view of my invention, and

Figure 2 is a cross-section of the same through theline x a: of fig. 1.

In this inventions. partition is used to separate the juice expressed between the first two rollers with which the cane comes in contact, from that expressed between the other rollers. The cane is'partially crushed between the first pair of rollers, so as to obtain only a pure, colorless juice. It is afterwards thoroughly pressed by the second pair, and all thejuice extracted. I l

' Similar letters of reference indicate corresponding parts in the several figures.

In the drawings, A represents the frame of my mill, and B B B are the rollers between which the cane is crushed. In fig. '1, both an upright and horizontal mill are shown, each having a similar set ofrollers. The juice expressed between the rollers flows down to the floor of the mill, and is received in a horizontal or nearly horizontal trough, G, which is divided longitudinally along-its centre by a water-tight vertical partition, 1). The though and partition are so arranged and situated that while the cane is passing between the two rollers '13 B, the juice expressed by them will flow into one apartment,'c, of the trough, and while passing between the other two rollers B B the juice expressed by them will .flow into the other apartment 0, and bekept separate from the juice expressed between the rollers B B. To thetop of the partition D, I aflix a curved plate, E, provided, on the side adjacent to the first two rollers B B, in the horizontal mill, with'a series of'perforations, e e e, to allow the juice falling upon the curved plate to run down into chamber 0. z is the discharge-port of chamber a, and z" of chamber 0. i l

It is designed by this construction to partially expresstne juice of the cane between the rollers 13 B, and keep this juice, which is clearand pure, entirely separate from the juice afterwards expressed, which is thick, of a dark grccncolor, impure, and of a. disagreeable taste. In a mill of this construction, the rollers 13 B should be set at a considerable distance apart, so as to only press out the pure juice, while the rollers 13 B should beset close together, in ordcr'to thoroughly crush the cane and extract all its fluids. When this is done the quality of molasses or sugar produced will be greatly improved by using my mill, the clear, palatable juice of the cane being kept entirely uncontaminated by admixture with the-impure juice afterwards expressed.

Myinvention is not limited to the use of the partition in a. mill having three rollers, but it may be applied to mills having any greater number, in which one partition, or more, may be used. It maybe applied to mills, the rollers of which work on journals bearing in fixed boxes, or to thoselmving rollers running in adjustable journal-boxes, by which the nearness of the rollers to each other can be regulated.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The, combination and arrangement of thecompartments c a, partition D, and curved perforated plate E, substantially as and for the purpose specified. l

Tothe above specification of my invention, I have signed my hand, this 8th day of October, 186?.

B. F. CAUFFMAN.
